Admin privilliges granted by an Admin group (when the user itself is not a direct admin) no longer work when the API Key is used to authenticate.
1.Create some user
2.Create a group and mark it as an Admin group (add the user into that group)
3.Try some admin-only action using the API Key (either with basic auth or the api key header) :
curl -XGET -u uriahl:AKCp5ZjzFrAR7dWgTbYMVBUSKnXrkoggs9vuSkcpmrd1T6db6WebT7RivLEiCeYoahVuea7Fc "http://localhost:8081/artifactory/api/system/configuration"
You'll get a 403.
